Made to order. Utility-spec irreversible grounding connectors ship from our production line, typically 6-8 weeks. Volume pricing: trade desk.
The Figure 8 compression ground rod connector joins 5/8 inch ground rods to 4-250 MCM copper conductors. The dual-cavity design permits two continuous parallel conductors in a compact form factor suited for direct burial applications. Pre-filled with anti-oxidant compound, the connector eliminates field preparation and reduces installation time. Electricians use this connector in grounding electrode systems, lightning protection networks, and utility substations where space constraints and environmental exposure demand reliable, code-compliant terminations.

Cross-Reference
Equivalent to Burndy and Blackburn compression ground rod connectors in the 5/8" rod size with 4-250 MCM cable range. Conversions Tech engineers this connector to the same electrical and mechanical performance standards at lower unit cost.
FAQ
Can I use this connector for two separate conductors or only continuous parallel runs?
The Figure 8 design accepts two continuous parallel conductors. Do not use for splicing two independent conductors; select a butt splice or tap connector for those applications.
Is additional anti-oxidant required for direct burial?
No. The connector arrives pre-filled with anti-oxidant compound. No field application needed.
Does UL96 listing satisfy NEC lightning protection requirements?
Yes. UL96 listing covers lightning protection system components per NFPA 780. Verify with your AHJ that the installation meets local amendments.

| Brand | Series / Part | Notes |
|---|---|---|
| Burndy HYGROUND / HYTAP | YGHR-class* | irreversible compression grounding, UL 467, direct burial - supply-house pricing typically 2-3x CT $42.90 |
| Panduit StructuredGround | compression grounding series* | match by conductor range |
| nVent ERICO | Cadweld (exothermic alt.) | weld-based alternative - compression installs faster, no powder/mold |
Where & why irreversible compression
NEC 250.64(C) requires grounding electrode conductors to be continuous or joined with irreversible compression connectors or exothermic welding - standard mechanical clamps are not permitted for buried or concealed GEC splices. These UL 467 listed connectors are rated for direct burial in earth or concrete. Range: 4-2/0 cable / 5/8 in rod.
How to crimp
Single crimp with a 12-ton class dieless or U-die hydraulic tool (Burndy Y35/Y750 class, index per size). CT stocks compatible crimp tools and dies at distributor pricing - the same tool runs our full lug and grounding line.
